June 24, 2025 – With extremely high temperatures and increasing humidity in the forecast, the Illinois Department of Transportation is cautioning the public to be on the lookout for pavement failures on roads throughout the state.
Pavement failures or blowouts occur when prolonged high temperatures cause the road to expand and buckle up or blow out, resulting in uneven driving surfaces. Precipitation and humidity increase the potential for buckling.
Pavement failures can be reported to IDOT by calling (800) 452-4368 or by reaching out to law enforcement.
For more information about pavement failures and how they occur, watch the video below created by IDOT.
